To remove an O-ring from a shaft: grip the o-ring with your thumb on one side of the shaft and a finger on the other side. Squeeze the o-ring between your thumb and finger while you slide them off the shaft to the side, stretching the o-ring. Have something handy, such as a toothpick, to slide under the o-ring as it stands proud of the shaft. Tada!
